Our spies have sent us a fresh batch of images with the highly anticipated second generation Audi R8.

Our spies have sent us a fresh batch of images with the highly anticipated second generation Audi R8.

The prototype was caught testing on the Nürburgring where Audi is celebrating last weekend's triumph at the 24-hour endurance race through a big R8 logo painted on the grass as a reference to its LMS ultra winning car. The car spotted was heavily disguised but our spies managed to grab a picture of the (unfinished) left door panel which looks considerably different compared to the outgoing model and it seems to boast a vertical air vent.

Set to come out sometime next year, the second-gen Audi R8 will continue with the usual naturally aspirated 4.2 V8 and 5.2 V10 engines but these will probably come with a minor power hike. The vehicle is expected to shave off around 130 lbs (59 kg) and will make use of a 12.3-inch digital customizable instrument cluster sourced from the 2014 TT.

It will retain the quattro all-wheel drive system and later during its lifetime will be offered with a smaller turbocharged engine working as the other motors with a 7-speed dual-clutch transmission.

Chances are Audi will decide to finally shows the revamped R8 before the end of the year, with sales likely to commence at the beginning of 2015.
